A couple of other problems exist, one is short term

A number of refineries are down, or have been down recently.
An east coast one had a power fail, that shuts them down for a day or so.
Several have been affected by the storms and flooding.

Then there is the switchover to summer gas.
While generally a god idea, IMHO it also causes grief because of the number of summer blends required.
The EPA should simplify it to maybe 2 or 3 blends nationwide, I heard there are 20 or 30 different blends depending on location.
